Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the B67 range.
Echinococcosis
An infection caused by the infestation of the larval form of tapeworms of the genus Echinococcus. The liver, lungs, and kidney are the most common areas of infestation.
Echinococcosis, Hepatic
Liver disease caused by infections with parasitic tapeworms of the genus ECHINOCOCCUS, such as Echinococcus granulosus or Echinococcus multilocularis. Ingested Echinococcus ova burrow into the intestinal mucosa. The larval migration to the liver via the PORTAL VEIN leads to watery vesicles (HYDATID CYST).
Echinococcosis, Pulmonary
Helminth infection of the lung caused by Echinococcus granulosus or Echinococcus multilocularis.
About the B67 Code Range
ICD-10 codes in the B67 series are used specifically to classify different forms of echinococcosis, a parasitic infection caused by tapeworms of the Echinococcus genus. These codes cover infections in various body sites, including the liver, lungs, bones, thyroid gland, and multiple or unspecified locations.
The ICD-10 code for echinococcosis helps healthcare providers document and differentiate between infections by Echinococcus granulosus and Echinococcus multilocularis. For example, B67.0 denotes Echinococcus granulosus infection of the liver, commonly referred to as a liver cyst or hydatid cyst, while B67.1 identifies lung involvement. Codes like B67.31 specify rare sites, such as the thyroid gland, and B67.90 is used when the infection site is unspecified but relevant synonyms include hydatid cyst of kidney and cystic echinococcosis. Other codes capture multilocular forms or infections affecting multiple sites. This structured coding allows precise recording and helps in recognizing terms like "hydatid cyst" or "larval echinococcosis" as part of echinococcosis diagnoses.
